What is required for adopting the "Previous Question" motion?

The motion to "Previous Question" is a procedural motion used to close debate on the current topic and proceed to a vote. This motion requires a two-thirds majority vote because it restricts the members' ability to discuss the issue further, which is a significant limitation on their right to debate. Requiring a larger majority ensures that there is substantial support among the assembly for moving forward without further discussion, reflecting a consensus that the matter is ready to be decided.

In contrast, the other options do not apply in the context of this motion. A simple majority vote would not be sufficient to impose such a significant restriction on debate, as it may not reflect a strong agreement among the members. Unanimous consent is rarely achievable in most assemblies, and requiring it for this motion would be impractical. While a quorum is necessary to conduct any business, it does not pertain to the specific voting requirement for the "Previous Question" motion itself. Thus, a two-thirds majority ensures that a significant portion of the assembly is in favor of moving quickly to a vote.
